一周特定时间部分的数据总和 - MS SQL 查询

Question

为了找到一周但下午 6 点到凌晨 12 点之间的特定时间的数据总和（在我的例子中是 CallsAnswered），我有以下一组查询，但它跳过了一天的数据在我的示例数据中。您能否验证我的查询并帮助我找到我遗漏的地方？

创建查询：

Create Table tblSingleBox (ScanDate DateTime, SkillTargetID Varchar(10), CallsAnswered int)

插入查询

Insert into tblSingleBox 
Values ('2018-02-18 19:17:01', '10888', 32),
('2018-02-18 23:59:59', '10888', 01),
('2018-02-19 00:10:01', '10888', 15),
('2018-02-19 17:59:59', '10889', 12),
('2018-02-19 20:59:59', '10889', 90),
('2018-02-25 21:59:59', '10889', 40)

查询:

SELECT convert(varchar(10),ScanDate,101)ScanDate,SkillTargetID, SUM(CallsAnswered)CallsAnswered
FROM    tblSingleBox (nolock)
WHERE    DATEPART(Hour, scandate) between 18 and 24
    and (scandate between '2018-02-18' and '2018-02-25')
GROUP BY    convert(varchar(10),ScanDate,101) ,SkillTargetID
order by convert(varchar(10),ScanDate,101)

预期输出：

ScanDate    SkillTargetID   CallsAnswered
18-02-2018  10888   33
18-02-2018  10889   11
19-02-2018  10889   90
25-02-2018  10889   40

我得到的实际输出：

ScanDate    SkillTargetID   CallsAnswered
02/18/2018  10888   33
02/18/2018  10889   11
02/19/2018  10889   90

Answer 1

scandate 有时间并且 2018-02-25 21:59:59 大于 2018-02-25（与 DATETIME 相比被视为 2018-02-25 00:00:00）。

所以将scandate转换为DATE（截止时间）或更改

scandate between '2018-02-18' and '2018-02-25'

到

scandate >= '2018-02-18' and scandate < '2018-02-26'
